MR> nothing beats self checkout.

It all depends on the size of the store.

I fancy self checkout in bigger groceries (Aldi/LIDL size minimum), but I also enjoy human driven in smaller stores. I totally don't get the idea of Amazon self-service stores. I was totally confused encountering one in London Wembley last summer. I couldn't even enter the store without installing some damn app. I said to the security guy at the front that I don't want any app just to buy a damn bottle of watter. He tried to be nice and offered help, but I said that I'll find another store faster than bother about this whole thing.

For stores with just one-two check outs and capacity to cover maybe 20-50 people, self checkout makes not much difference to me.
